Does Spiderwort like sun or shade ?

We recently moved into a new home and discovered that we have 4 spider
wort plants. We never had these before and do not know how to care for
them.
When we moved in they were about 6" tall and now they are 24"tall. They
have
fallen over due to the weight. They continue to bloom beautiful blue
flowers
each morning and close at night. Come this fall what steps need to be
taken.
Do you cut them back or let nature take its course?
